VEHICLE FRAME sILL.

Application mea umn ao, 1927.. serial Ng. 179,563.

`substantially similar to the main portions of the sills used in various types of motor vehicles such as those of the street car type, double deck bus type and parlor car bus type.

In forming the sills for vehicles a dieis usedl as is well known, and the present invent1on' contemplates the use of a single die for fornr, ing a sill portion or section for these various types of vehicles and in utilizing the sill formed by said die for attaching extensions to accommodate various types of vehicle bodies.

Reference is had to-'the accompan ing*l drawings which illustrate the preferred ormy of the invention; though it is to be understood that the invention is not limited tothe exact details of construction shown and de-4 scribed, as it is'obvious that various modifications thereof within the scope of the claimsy will occur to persons skilled in the art. AIn the drawings: u Figure l is a diagrammatic side elevation of1 a motor vehicle embodying my improved Figure 2 is a fragmentary side elevation ofv the frame sill; Figure 3 Ais a top plan view ofthe same;

Figure 4 'is a fra mentary'side'elevation of y a modiedform o sill;

view taken on line 5-5 ofFigure 2,' and g Y Figure 5 is a verticaltransverse sectional4 f Figure 6 is asimilar view taken on line Referrin now more designated enerally as A and an extension secured to e rea-r end of the main portion,

'. the extension being designated generally as B.

The main ortion of the side sill is formed by a standard die and is substantially a vchanparticularly to the: drawings t e invention contemplates the pro vision of a side sill having a main portion nel having a web 5, a top chord 7 and a bottom chord 48, as clearly shown in Fig. 5. They rear end of the main portion is arched yas shown at 6 and has secured thereto the extension B. Said extension B is also a channel having a web 10, .and top and bottom chords 11 and 13 respectively, as clearly indicated in Fig. 6. The forward end of the extension is arched as at 14 and said archli is of greater heightlthan'thel beforementioned arch, although for the'major portion thereof 'the arch 14 is complemental tothe arch 6 whereby to bev received within the channel in close :fitting engagement there-y with` asshown in Fig. 5 and to be secured thereto by rivetsv 15 or the like. 'A

The invention shownis particularly de-v signed for use with vehicles having a rear' exit, and in. such a type of vehicle, it is de-. f

sirable that the rear platform be. arranged relatively vlow in order to provide a construction which will permit easy egress `to passengers from the vehicle. To that end, the arch 14 is, as before-mentioned, of greater height thanl the arch 6 whereby when the two sections are assembled in connected relation,"the extension B will be 'arranged in a horizontal plane which is 'lower than the of the arch.l To effect this arrangement, the lower chord 8 ofthe main portion'A is cut as at 13 and from this point to the end of the main portion the lower chord is strai htened in line with the web 5 forming a wide web yhorizontal plane of the'main section '5 ahead strong and durable connection of the rear end of the arch 6 with the extension B and reinforcing the rear end of the arch 6 and effecting a relative arrangement for positioning of the section Aand extensilon'B such that the latter is arranged in a lower horivzvontal plane than the main ortion A'whereby the rear platform of a ve icle may be supported in a relatively low plane. .The sill shown in Fig. 2 is provided with a relatively embraced bythe other arch, the rear section being arranged with its upper face disposed below the upper face of the main sill section to accommodate a motor vehicle rear platform thereon, and fastenings rigidly connecting the two arches together.

2. A vehicle frame sill comprisingr a main section having an arched rear end and an auxiliary section secured to the arched end andarrangedl in a lower horizontal plane than the main section. t

3. A vehicle frame sill comprising a main section havin an arched-rear end and an auxiliary section having an arched endV se- 'cured to the arched rear end of said main section and so connected thereto as to lie in a horizontal plane lower than the plane of the main section.

4. A vehicle frame sill com rising a. main section of channel form having an arched rear end, and an extension having an arched end complemental with the arched end of the main section secured to the main section and arranged in a horizontal plane below the main section.

5. A vehicle frame sill comprising a main moana section of channel form having .top and bottom chords and a web, said section having its rear end arched with a portion of the bot tom chord formed into the web, and an ex,- tension having an arched end secured to the arched end of the main section, the arch of the extension being of greater height than the arch of the main section whereby when the main section and extension are connected together the latter is arranged in a lower horizontal plane than the main section.

(i. Avehicle frame sill comprising sections cach having an arched end by which they are connected, one of the arches being of greater height than the other whereby when said sections are connected one thereof arranged in a horizontal plane lower than the other.

7. A chassis frame side member comprising sections` having connected arched ends with one of said sections arranged in a horizontal plane lower than the other section whereby to provide a low support for the portionv of a vehicle body arranged over said section.

8. A sill comprising a main section of channel s hape for a portion of its length and angle-shaped at its end and being arched within both the channel and angle shaped zones, in combination with a channel shaped auxiliary section having an arched zone lapping and being secured within the arch of said main section.

In Witness whereof I have hereunto set my hand.
